Geographic Information Systems - GIS
Welcome to the City of Pullman's GISThe goal of the Geographic Information System (GIS) is to develop location intelligence across the City of Pullman. Location is the common thread connecting the physical and intangible resources of the City. The tools of the GIS enable the City to:
- Collect location information
- Visualize, analyze and understand spatial relationships
- Engage and communicate through maps and mapping applications
- Connect location information to other business intelligence systems
GIS Map Portal
Maps and data on the City of Pullman Geographic Information System (GIS) are representations of real-world conditions. With consideration for the intended use of the map, appropriate effort is made to ensure the accuracy of the data, but errors in mapping and errors in source documents do occur. As such the City of Pullman assumes no liability for errors, omissions or inaccuracies regardless of cause, or for any decision made, action taken, or not taken, as a result of reliance upon any maps.
Potential Sources of Mapping Error
The data contained in basemaps on this site was derived in part by humans, digitizing from aerial imagery and in part by computer algorithms extracting features from aerial imagery. In each case classification errors can occur, obscured features may be missed, and positional accuracy is limited to the resolution of the aerial image.
- Basemaps are representations of real-world conditions, but confirm on-the-ground conditions before making decisions or acting on information.
- The location of property boundaries must be determined by a land surveyor registered to practice in the State of Washington.
- Utility maps should not be used in lieu of authorized (811) utility locates.
- Timing, scale, and location method will affect the “accuracy” of a data set.
- Even if location data is very accurate, it might look like it is in the wrong place, relative to the basemap.
- Location errors are unavoidably introduced by representing the earth as a flat map.
Appropriate Map Use
- DON’T: Make decisions or act without confirming on-the-ground conditions.
- DON’T: Assume that, because utilities are not shown on a map, that utilities don’t exist in that area.
- DO: Use maps to help find assets on the ground.
- DO: Contact City of Pullman GIS with questions regarding accuracy and completeness of maps.
